WINDOW-SCREEN.

Specification of Letters Patent.

Patented J une 25, 1918.

Application filed May 31, 1917. Serial No. 172,017.

To all whom it may concern:

Be it known that I, EMIL E. PEDo, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinventedcertain useful Im provements in Window-Screens, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention has reference generally to improvements in that class ofinventions known as rolling window screens and more particularly relatesto a window screen.

As the primary aim and object this invention contemplates the provisionof a window screen which will adequately prevent the passage of insectsan'd the like into a room or other inclosure when arranged in a closedposition and which may be rolled up out of the way in the manner ofwindow shades when not in actual use.

It is an additional object of this invention to provide a device of thecharacter mentioned wherein the window screen can be readily rolled upand will be prevented from spreading or becoming distorted.

The invention as a further improvement consists in the provision of a'window screen wherein a tight closure will be ei'ectedbetween the windowframe a'nd the ends and sides of the window screen.

Among the other aims and objects of this invention may be recited theprovision of a device of the character described with a view tocompactness, and in which the number of parts are few, the constructionsimple, the cost of production low and the efficiency high.

Other'improvements and novel details of the construction and arrangementof parts of the apparatus will be brought out more in detail in thedescription to' follow, which for a clear understanding of the inventionshould b e considered in connection with the accompanying drawingsforming a part hereof, and wherein is disclosed for the purpose ofillustration a convenient and satis factory embodiment of the invention.It is to be noted in this connection that minor changes in theconstruction and arrangement of parts may be made without departing fromthe principle of operation of the various parts.

The preferred embodiment of the present invention is clearly illustratedin the accompanying drawings, in which- Figure 1 is a perspective viewshowing the device applied to a window frame;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a detail of one of the roller brackets;

Fig. 4 is a transverse cross section of the window screen guide.

Similar characters of reference are employed in all the above describedviews, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there isprovided for the purpose of enabling a clear understanding of thepresent invention a window frame including sides l and a head 2 of anyconventional form, and it is to be under stood that the construction ofthe frame forms no part of this invention.

- With a view toward providing improved supporting means a pair ofsubstantially rectangular plates 3 are employed and are attached to theinner surfaces of the sides 1 adjacent the head 2 being arranged inopposed relation with respect to each other. Each plate is provided withopenings 4 ad jacent the respective ends for accommodating securingdevices 5 which are anchored in the sides and one plate is also providedwith a slot 6 while the other plate is formed with an opening 7positioned opposite to the slot 6for a purpose that will becomeapparent. The screening means in the present instance consists of aspring roller 8 similar in construction to the conventional window shaderoller but possessing a stronger spring action. One of the trunnions 9projecting from one end of the roller is journaled in one of theopenings 7 while the other trunnion 10 on the opposite end of the rolleris rectangular in cross section as is common in spring rollers and ismounted in the opposite slot 6 in a substantially stationary position aswill be apparent. A piece of screening 11 formed of suitable mesh fabrichas one end rigidly secured to the spring roller 8 and is windablethereabout while an elongated bar 12 is mounted transversely of theouter end of the screen 11 and serves in ei'ect as a weight to hold thescreen taut when in an extended position Vso as to close the windowframe.

Cooperating with the screening when it is a en it is not desired to usethe screenin in an extended posltion are the guides 13 in the presentinstance formed of stri s of metal channel shaped in cross section. heseguides are secured in opposed relation on the inner surfaces yof thesides of the frame and vertically thereof terminating at the lower edgeof the plates and at the sill of the window frame. The side edges of thescreen when in an extended position are arranged in close relation withthe guides so as to pre,- vent the passage of insects into the room orother inclosure. t

As .intimated means haye been provided for preventing the screening fromspreading out when it is being rolled up into a closed position and inthe present instance' consists of a guide roller 14 the trunnions 15 onthe respective ends of which are journaled in the openings 7 on theplates and when this roller is in the position described it is arrangedin close spacedrelation with the outer surface of the spring roller 8. vf

In use, assuming that the parts have been assembled in themannerdescribed to close the window frame by. the screen it is only necessaryto engage the bar 12 and pull downwardly against the tension of thespring roller 8 whereupon the screening will be unwound from the roller8 and will be guided `during this downward movement by the guides 13. 0f.course when the bar ispositioned near the silleof the frame downwardmovement may be stopped to allow the spring roller to stop as is thecustom in usual window shades and by reason of the fact that this bar isarranged against the sill and vthe sides ofthe screening 11 are arrangedin close relation with the guides 13 it will be appreciated that insectswill be prevented from ssing intol the room or other inclosure.

it is only necessary to fasten the bar l2 to give it a slight jerkwhereupon owing to the tension of the spring roller the screening willbe automatically rewound and during this action the guide roller 15 willserve to prevent spreading thereof.

As' many changes could be made in the above construction and manyapparently widely different embodiments of this invention could 'be madewithout departing from the scope of the invention, it is intended thatall matter contained in the above `description or shown in theaccompanying drawings shall be interpreted as illustrative and not 'in alimited sense. It is also to be understood that the language used in thefollowing claim is intended to cover all the generic and specificfeatures of the invention herein described and all statements of thescope of the invention, which as a matter of language, milght be said tofall therebetween.

aving thus fully described this invention,

what is claimed as new and desired to be secured by Letters-Patent, isz-n the lower edge of the plate and the sill of the frame for guidingthe movement of the iece of screen and for coperating therewit inpreventlng the passage of insects through the frame, an elongatedtransverse bar carried by the outer end of the piece of screening andoperating between the guides to serve dual for the purpose of acting asa weight to hold the piece of screening taut when in an extendedposition and for coperating with the sill of the frame for preventingthe passage of insects through the frame, and a guide roller mountedbetween the plates and Y coperating with the screening for preventingthe same from spreading during actuation.

In testimony whereof I ax my signature.
